An embodiment is a physiological and cognitive feedback device, system, and method for evaluating a response of a user in an interactive language learning advertisement. Foreign language lessons are provided at no cost to consumers online in exchange for the consumers' feedback on the products or services embedded in the language lessons. The language lessons may use television advertisements as course material, serving both educational and promotional purposes. Revenues are generated through product placement opportunities as well as consumer survey responses that are a part of the lessons.
